'He is so young and has a lot of
responsibility on his shoulders, becoming the administrator of his
mother’s estate,' the source said.

Conor's half sister, Kick, 24, told
the Post: 'Conor has the biggest heart in the world, and Taylor is
lovely. It’s been a tough summer, and I hope he gets to enjoy a little
peace now.'

She, like Conor, has been concentrating on volunteer work to help grieve the family's loss, working at Bellevue Hospital.

The other Kennedy kids have taken on
similar projects, with 16-year-old Kyra going on a church mission in
Africa while 14-year-old Fin went to a ski camp.

Over the past few days Taylor and Conor's Love Story has been gathering pace.

The country singer headed home to Nashville this week to introduce her new boyfriend to her parents.

Excited fans posted pictures of them on Twitter, as they explored her adopted hometown.

And Taylor's parents, who are currently undergoing a divorce, even reunited to share a meal together and meet their daughter's beau.

Taylor and Conor visited the Pancake Pantry, Starbucks, and various other low key eateries as they looked around.

Her fans were delighted to catch sight of Taylor in the flesh.

'This day is the best day of my life,' a fan named Abby wrote on her Tumblr page. 'I met Taylor Swift with my absolute best friends like we said we would do one day. We saw her with her new boyfriend.

'We told her how happy we were for here and she had the biggest smile on her face. God is so good.'

Taylor has been dating Conor, the son of Robert F. Kennedy Jr. and the late Mary Richardson Kennedy, for about two months.

She
has already received the seal of approval from her boyfriend's family,
after she joined the Kennedy clan at their Cape Cod vacation compound.

His grandmother, family matriarch, Ethel, 84, even told journalists at a recent Television Critics Association event in Beverly Hills that the family 'should be so lucky' to welcome Swift into the fold.

The couple were brought together by Conor's aunt Rory Kennedy after she attended one of Taylor's concerts with her two daughters.

Rory, who directed Ethel, the upcoming HBO documentary about the family matriach, gushed that Taylor 'is a great friend of all of ours.'

Adding: 'We love her. She's awesome.'

Taylor told Vogue earlier this year that she's a great admirer of the Kennedy clan, describing the moment she met Ethel Kennedy as 'the only time in my life I have ever been starstruck.'

Taylor certainly deserves a positive spell in her love life, following a string of high-profile romance flops with Taylor Lautner, Joe Jonas, John Meyer and Jake Gyllenhaal.
